Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image processing systems, particularly for X-ray images, setting effective image processing parameters for diagnosis is challenging due to the large number of combinations required, leading to cumbersome operations for operators, and existing techniques often fail to provide exactly matched sample images, resulting in unsatisfactory image processing outcomes.
Innovation Solution
An image processing apparatus and method that display multiple sample images generated by varying image processing parameters, allowing operators to set parameters using a mixing ratio to interpolate desired image processing settings, thereby simplifying the process and ensuring consistent image quality for diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all images assumed to be desired by operator are prepared, then the image exactly matched with image desired by operator can be obtained, but the number of sample images to be prepared is huge and operator should perform very troublesome operations to select image from huge number of sample images
Solution Approach 1:
The patent changes the parameter of image presentation from displaying all possible sample images to displaying a limited number of representative sample images. By selecting key parameter combinations that cover the main diagnostic requirements, the system reduces the number of images from potentially thousands to a manageable set, while still enabling operators to obtain desired images through parameter adjustment rather than manual selection from overwhelming options.
2Device complexity
If image processing parameters are simply changed, then the number of sample images to be prepared is reduced, but the limiting conditions for X-ray image cannot be satisfied
Solution Approach 1:
The patent applies preliminary action by pre-calculating and pre-presenting a limited set of representative sample images that satisfy diagnostic limiting conditions. These sample images are prepared in advance with carefully selected parameter combinations that ensure diagnostic quality, allowing operators to directly access reliable results without needing to manually adjust parameters that might compromise image quality.
Solution Approach 2:
The system incorporates feedback mechanisms where operators can provide input on desired image characteristics, and the system responds by adjusting parameter selections from the pre-prepared sample images. This feedback loop ensures that the final selected images meet diagnostic requirements while avoiding the complexity of generating all possible parameter combinations.
3Manufacturing precision
If a large number of image processing operations are performed, then better images can be obtained, but the number of combinations of image processing parameters is large and it takes very long time to obtain desired parameter through trial and error
Solution Approach 1:
The patent performs the time-consuming image processing operations in advance to create a library of pre-processed sample images with various parameter combinations. By completing these complex processing tasks beforehand, the system eliminates the need for operators to perform lengthy trial-and-error adjustments during actual diagnostic work, significantly reducing time loss while maintaining high image quality through the pre-computed parameter optimizations.

AI summary
A system control unit causes a diagnosis monitor to display a plurality of sample images generated by changing one or more image processing parameters used in image processing of an X-ray image. When an operator designates a mixing ratio, at which the sample images are mixed, after the plurality of sample images are displayed on the diagnosis monitor, the system control unit sets one or more image processing parameters to be used when image processing of an X-ray image is performed based on the designated mixing ratio. An image processing unit performs image processing of an X-ray image input from an image input unit based on the set image processing parameter.
